. '1 Claims. (01. a-ma This invention relates to the production of rubber gloves for use in protection of hands in contacting fiuids of various kinds and classes. More particularly, the invention deals with the producticn of a glove of this kind on a mould in such manner as to produce a plurality of longitudinally extending ribs or indentures in the glove in order to space part of the. hand and fingers of the hand from parts of the inner surface of the glove to allow for ventilation of air through the glove. to strengthen the glove and, further, to facilitate placement of the glove upon the hand.

The novel features of the invention will be best understood from the following descriptions, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which,-the separate parts are designated by suitable reference characters in each of the viewsand, in which:

Fig. 1 is a view of the back of a glove arranged on the mould employed for forming the same.

Fig. 2 is a face view of the palm of the glove; and

Fig. 3 is a section on the line 3-3 of Fig. l, indicating in dot and dash-lines the position of fingers in the glove structure as and when the mould is removed, and omitting all background showing.

In practice, I employ a mould ll shaped or patterned from a human hand with the hand in a slightly curved and natural position, and different from the human hand solely in providing, between the fingers, web portions, so that the resulting glove H will have, between the finger portions l2 and I3, 9. web M; between the finger portions l3 and H5, a web 16 and, between the fingers l5 and IT, a web I8, the web running to a point substantially adjacent the outer joints of the fingers. The webs l4, l6 and I8 will form, between the fingers of the hand, air spaces i8, 20 and 2|, respectively, as will clearly appear from a consideration of Fig. 3, in which figure, the four fingers have been outlined in dot and dash lines at 22, 23, 24 and 2!.

The mould ID has, on the back portion thereof, a plurality of grooves 26, I1, 28, II and 30 which extend from the wrist portion of the mould to a point short of the finger knuckles and, then,

ribs serve to partially space the fingers from the surface of the glove to permit air to extend into, as well as out of the glove and to enter the spaces .'8, 20 and 2!. This facilitates ventilation of the glove and also mounting of the glove upon the hand, allowing the air within the glove to be exhausted in the operation of inserting the hand into the glove.

The palm portion of the mould also has a longitudinal groove 36, note Fig. 3, which extends from the wrist portion to and short of the tip of that part of the mould which forms the finger ii of the glove. The groove 38 forms a corresponding inwardly extending rib 31.

The thumb portion of the glove is shown at 88 and this thumb portion is formed in its conventional arrangement with the hand and exclusive of any webbing, so as to allow the thumb to flex freely in grasping objects. While the fingers are maintained substantially in a close environment one with respect to the other, the web portions l4, I6 and ill will facilltateslight spreading of the fingers, particularly in the operation of grasping objects in the hand. However, in most instances, the spreading of the fingers isnot essential. The resulting glove structure is a modified formof mitten, the tips or outer end portions of the fingers being free, thus enabling the tips of the fingers to have a relative movement one with respect to the other, as and when this is desired.

In forming the glove, the body of rubber is applied to the mould in any of the known processes and one known procedure which is probably prefcrable would be to use the dipping process so as to provide a substantially even wall thickness throughout the entire glove, excepting that the slight enlargement in wall thickness may result in the rib portions 3l--35 and 31. This will be desirable, however, as it will give tothe glove a reinforcement which will take up the stress and strain of pulling the glove upon the hand, as well as in removal of the glove from the hand. These reinforcing members will prevent tearing of the glove to a large degree and will also facilitate reducing wall thickness of the remainder of the glove, so that the glove as a whole would become more comfortable upon the hand. By spreading or diverging the ribs to the sides of the fingers and thumb. in the manner shown, the joints or knuckles will be free to extend themselves in the operation of bending the hand.

In other words, this will produce no discomfort to the wearer as would otherwise be the case, if the ribs were disposed upon the high points of the joints or knuckles. Furthermore, this construction spreads the reinforcement and opens the air channels which would be formed at opposite sides oi the ribs to the spaces I9, 20 and II.

The single rib 31 on the palm of the hand serves to ventilate this portion oi the hand and this rib will not, by reason of its location, materially interi'ere with the use of the hand in grasping obects.

1 At the end of the wrist portion of the mould I is formed a threaded socket 39 which facilitates mounting oi the mould upon a suitable support in the operation of moulding and vulcanizing the glove thereon. For sake of description, the glove, in addition to the finger and thumb portions, includes a hand portion 40 and a wrist portion ll.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A rubber glove comprising wrist, finger and thumb portions, the finger portions of the glove having short ends and being Joined by web portions forming, within the glove between adjacent fingers, inwardly oi the finger tips, air spaces, and means comprising inwardly extending ribs opening through the edge 01' the wrist portion and extending to the short finger ends to circulate air to said spaces when the glove is on the hand.

2. A rubber glove comprising wrist, finger and thumb portions, the finger portions of the glove having short ends and being joined by web portions forming, within the glove between adjacent fingers, inwardly oi the finger tips, air spaces, means comprising inwardly extending ribs opening through the edge of the wrist portion and extending to theshort finger ends to circulate air to said spaces when the glove is on the hand,

and said ribs being arranged longitudinally of.

the wrist, hand and finger portions of the glove.

3. A rubber glove comprising wrist, finger and thumb portions, the finger portions of the glove having short ends and being Joined by web portions forming within the glove between adjacent fingers, inwardly oi the finger tips, air spaces, means comprising inwardly extending ribs opening through the ends of the wrist portion and extending to the short finger ends to circulate air to said spaces when the glove is on the hand, said ribs being arranged longitudinally of the wrist, hand and finger portions of the glove, and another rib extending along the wrist and hand portion onto the thumb portion of the glove.

4. A rubber glove comprising wrist, finger and thumb portions, the finger portions of the glove having short ends and being Joined by web portions forming, within the glove between adjacent fingers, inwardly oi the finger tips, air spaces, means comprising inwardly extending ribs opening through the edge of the wrist portion and extending to the short finger ends to circulate air to said spaces when the glove is on the hand; said ribs 'being arranged longitudinally of the wrist, hand and finger portions oi the glove, another rib extending along the wrist and hand portion onto the thumb portion of the glove, and a rib extending longitudinally of the wrist, hand and one finger of the glove at the inner or palm portion of the glove.
